PURPOSE
The aim of the study was to explore a potential dose effect of water on heart rate responses and markers of vagal tone modulation.
METHODS
This was a randomized crossover study involving eight men whose heart rate and heart rate variability parameters were continuously measured following ingestion of different volumes of still mineral water (200, 400, 600, and 800 mL).
RESULTS
A significant volume by time effect for heart rate (p < 0.005) was observed. Ingestion of all volumes of drink water of more 200 mL significantly decreased the heart rate. Significant time effects for heart rate variability parameters were observed.
CONCLUSION
Ingestion of a mineral water drink affected the heart rate in men in a time-dependent manner, possibly by changes in cardiac vagal modulation.
目的
本研究旨在探讨水对心率反应和迷走神经张力调节标志物的潜在剂量效应。
方法
这是一项随机交叉研究，涉及 8 名男性，在摄入不同体积的静止矿泉水（200、400、600 和 800 毫升）后，连续测量他们的心率和心率变异性参数。
结果
心率存在显著的体积-时间效应（p<0.005）。摄入超过 200 毫升的所有水体积均显著降低了心率。心率变异性参数也存在显著的时间效应。
结论
水的摄入以时间依赖的方式影响男性的心率，可能是通过改变心脏迷走神经调节。
